Abstract. WATEQB is a BASICA revision for IBM PC of WATEQF, a geochemical model for chemical equilibrium and saturation of natural waters. This model computes the speciation of inorganic ions and complex species in solution for a given water analysis.
WATEQB is identical to the FORTRAN IV version from the standpoint of chemical process; however, the structure of the program differs from the original version. The structure of the program is not complex and allows the user to try some new modifications, if necessary.
Due to the limited memory of personal computers and in contrast to the large volume of the original version of the program, the author has created four data files, one of which is of random access type. Reading the thermochemical data is possible through these four data files.
This paper demonstrates how to set up the input data to execute WATEQB and describes the program rather than the model. The users of WATEQB will increase as personal computers become more common. 相似文献

Historically, specific capacity information has been used to calculate aquifer transmissivity when pumping test data are unavailable. This paper presents a simple computer program written in the MATLAB programming language that estimates transmissivity from specific capacity data while correcting for aquifer partial penetration and well efficiency. The program graphically plots transmissivity as a function of these factors so that the user can visually estimate their relative importance in a particular application. The program is compatible with any computer operating system running MATLAB, including Windows, Macintosh OS, Linux, and Unix. Two simple examples illustrate program usage. 相似文献

Hierarchical clustering is a powerful tool for evaluating multivariate data as for instance about water samples. Results are illustrated by dendrograms which can be understood not only as means of classification but also as a kind of object display. It seems reasonable to preserve as well as possible original inter-object distances within the dendrogram. For the classical hierarchical algorithms a correction by index adjustment is proposed. This procedure may lead to more reliable results. Practical and simulated data examples are discussed. A formula for distance-updating in the case of relative distance preservation is constructed. Finally an advanced version of the program HIERAG in Turbo Pascal is listed. This program uses INTEGER-type variables for inter-object distances instead of REAL-type ones. 相似文献

The Groundwater Monitoring Program at the Savannah River Plant currently consists of more than 700 wells at more than 70 sites, and growth is projected. The organization and operation of the program has been designed to support an active drilling program, the acquisition of a large amount of repetitive data, the generation of numerous reports, associated QA/QC controls, and provisions for additional growth. The design is centered around two key features—modular components and computer usage.
The modular component concept is an organizational tool that gives one group responsibility for a specific portion of the program. This responsibility includes the operation of its segment and the coordination of operations with the other groups in the program.
Computers, the associated software programs, and a simple set of rules (the sampling guide) enables the program to accommodate large amounts of repetitive data in a timely, uniform manner. Feedback loops are included to ensure that new data are incorporated into future program decisions (new sample schedules and well locations). The highly automated system determines new sample schedules, collates/reviews incoming data, and generates various reports. Six reports are issued on a regular basis, from quarterly to annually, to ensure that the program is adequately documented.
The program has been in successful operation for more than a year and has accommodated the expected growth. 相似文献
